Hi monks,

I'm trying to sort number-letter sequences in descending order but my code doesn't produce the desired result. 
use strict;

my @array = qw(2aa 2ba 12kf 9cn 9vn 21sg);
my @sorted = join("\n", sort {$b <=> $a} @array);
print foreach @sorted;

# Output
21sg
12kf
9vn
9cn
2ba
2aa

[download]
The desired output is:

21sg
12kf
9cn
9vn
2aa
2ba

In other words, I need the sorting to take into account the letters as well.

How do I accomplish that? I look forward to reading your solutions. Thanks in anticipation =)

cheers
